GM4ULS ham radio station

Just when you thought it was safe to beam in the right direction…

BD7IS

Yesterday at about 11:00 UTC (11am local) I decided to switch on 10m for a few minutes, to see what was doing. There were rock-crushing signals from Russia and the Ukraine – and I mean like +60dB – and there was this lone voice on 28.510, BD7IS. I noticed a couple of weird things. Firstly there was a string of stations in England working him, and I could hear every single one, which is a fairly unusual phenomenon as regards skip distance. Secondly he was almost inaudible when I set my beam to the shortest great circle path for Guangzhou, and 57 when I beamed South-West. I could only conclude that this was another example of long path propagation, totally unexpected.

The last time that I worked anyone on long path it was Australia, and I guess that means that this contact with China means in fact that my signals travelled further to a station in QSO. However, I recalled the distance travelled by my signals in the QSO with VK7ZX (see previous post).

I know none of this is outstanding, ground-breaking stuff, but I guess this blog is good for recording the minutiae of the life of an ordinary ham…

    Very nice!

    Long path, short path, I can’t tell the difference. Just a poor man’s vertical doing the job here.
